INVENTION
Russian Federation Patent RU2099415
HOUSEHOLD APPLIANCE methane fermentation
Name of the inventor: Viktor Tumchenok Ignatievich
The name of the patentee: Tumchenok Victor Ignatievich
Address for correspondence:
Starting date of the patent: 1995.01.17
Usage: when the anaerobic treatment of manure, dung, faeces, carbon-containing solid waste, biogas for heating, cooking, water heating in cottages, holiday homes, backyard farms. Essence: household device methane fermentation comprises a body divided into chambers acidic, neutral and alkaline methane fermentation with partitions made in their windows for the passage of the substrate. Fastened on the drive shafts mixing elements. They are installed concentrically with shells racks arranged to form a gap therebetween circulation. In the acid fermentation chamber having a perforated bottom arranged spray tank with the drive shaft and the grinding elements. The charging device has a sealing lid and a hydraulic valve disposed in the spray tank.
DESCRIPTION OF THE INVENTION
The invention relates to devices of anaerobic digestion of manure, dung, faeces, carbon-containing solid waste, waste water and can be used to produce biogas for heating, cooking, water heating in cottages, country houses, farms farmsteads.
Known methane fermentation apparatus comprising a housing with technological partitions and nozzles supply and removal of media (VG Janko Janko G. "Treatment of waste water and sludge in the digesters," Kyiv, 1978, p.40, Figure 8) in which a low degree of fermentation as a substrate involved in the fermentation of microorganisms waste products oppress each other.
Known household methane fermentation apparatus comprising a housing with partitions mounted to form chambers acidic, neutral, alkaline, and methane fermentation, reported the windows, made alternately on the top and bottom walls for the passage of the substrate from the loading to the unloading device (Viesturs C.E. Kuznetsov .M. Savenkov V. fermentation systems, Riga, 1986, p. 18, fig. 22). The device closest to the present invention by the technical essence and achieved result. However, in this known apparatus is low fineness suspensions substrate under stirring, which reduces the efficiency of the apparatus.
The present invention is directed to the achievement of the technical result is to increase the efficiency of the apparatus.
This is achieved in that the consumer unit methane fermentation, comprising a housing with baffles mounted to form chambers for acidic, neutral, alkaline and methane fermentation reported by windows alternately executed from the top and bottom walls for passage of the substrate from the feed device to the discharge, characterized by that the device is provided with mixing elements mounted on the drive shafts and concentrically them installed racks of the shells, fixed to the uprights with gaps for circulation of substrate between them, and the charging device is provided with a sealing cap at the top and water seal at the bottom, placed in extender container interacting with the acid fermentation chamber through the perforated bottom, the container is placed in a shaft equipped with a driven grinding elements.

FIG. 1 shows a household apparatus methane fermentation, longitudinal section, FIG. 2 section AA in FIG. 1.
Household apparatus methane fermentation comprises a housing 1 with partitions 2, mounted with the formation of chambers 3, 4, 5, 6, respectively, acidic, neutral, alkaline and methane fermentation communicated with each other windows 7 are alternately executed on the top and bottom walls 2 for the passage of substrate from loading device 8 to the unloading apparatus 9. The device is provided with mixing elements 10 mounted on shafts 11, 12 provided with drives.
Mixing elements 10 concentrically of the shaft 11 the rack 13 mounted to the shells 14, 13 fixed on the struts with gaps for circulation of substrate 15 between them.
The loading device 8 is provided with a sealing cap 16 at the top, water seal 17 at the bottom, placed in the container 18 Extender interacting with the chamber 3 for the acid fermentation through the perforated bottom 19, a container 18 is placed a shaft 20 provided with the drive 21 and the grinding elements 22. The grinding elements 22 are arranged so that they coincide with the static shaft and rotating it away from the substrate with an increase in the processing region and providing suspensions grinding to a particle size comparable to the size of the microorganisms: kislotogenov. acetogenic, atsetogidrogenov and methanogens. The camera 6 for methane fermentation is made with an explosive valve 23, a hydraulic gate 24 and drain pipe 25 biogas.
Household methane fermentation apparatus operates as follows.
After loading device 8 when the cover 16 is carried load capacitance extender 18, wherein when the shaft 20 is rotated by the actuator 21 occurs suspensions grinding shredding elements 22 which diverge away from the shaft 20 under the action of inertia forces. The concentration of suspended solids in the substrate take 4-5% and the ratio of 20: 1. The bottom slurry through perforations 19 pass into the chamber 3 of the housing 1 acid fermentation through the windows 7 and substrate passes sequentially chambers 4, 5 and 6. Each cell is performed while stirring regrinding suspensions members 10 when the shaft 11 is rotated by the actuator 12, and between the elements 10 and struts 13 having shear forces. Simultaneously, the shell 14 is formed circulation circuits, which increase the multiplicity of effects on the suspension elements 10 in the substrate. Filling body 1 substrate was performed on 4/5 of the volume, with 10 mixing elements destroy the crust on the surface of the substrate and stirring the sediment on the bottom of the housing 1. The chamber 6 is formed in the methane fermentation biogas through the hydraulic valve 24 is removed through the conduit 25 to the consumer. The housing 1 is performed without thermal insulation and the process of fermentation is carried out at a temperature of 18-24 o C with thermostatic heat the room where the machine is installed. The level of the substrate in the housing 1 is set at the level of its gate 17 in the hydraulic loading device 8. The batch through the feed device 8 and discharge through the device 9 is performed periodically in a continuous process of digestion in the body 1 and frequency of mixing and milling drives 12 and 21. Suspensions consistently mixed from the feeder vessel 18 through 8, its perforated bottom 19, pass through the windows 7 in the cells 3,4,5 and 6, in the form of their poslebrozhevogo residue withdrawn through a discharge device 9, for example, into a container (bin) for use in as biofertilizers. The device allows you to dispose of waste paper, waste processing vegetables, fruits, vegetable residues garden equipment, fecal population, manure and litter of animals and birds. The hydraulic valve 17 and the sealing cover 16 eliminate the likelihood of odors in the room where the machine is installed. Shafts 11 and shaft 20 are sealed, and eliminates odors and methane in the room
Operation of this device may provide improvement of the ecological situation around the object, in which the machine is installed. Using its profitability.
